html - 如何在不相交的情况下制作粘性侧边栏

我有两个粘性的导航栏。问题在于它们都在页面的左上角相交，并且导航栏与顶部的相交，从而阻塞了按钮。我已经尝试增加填充，但是两个导航栏相交处仍然存在一个不可见的空间。我想做的是将侧边栏放在顶部边栏下方，并且它们不相交并阻塞按钮的一部分。到目前为止，这是我的代码：



.button {
  display: inline-block;
  border-radius: 4px;
  background-color: #4CAF50e;
  border: none;

  text-align: center;
  font-size: 28px;
  padding: 20px;
  width: 200px;
  transition: all 0.5s;
  cursor: pointer;
  margin: 5px;
}

.button span {
  cursor: pointer;
  display: inline-block;
  position: relative;
  transition: 0.5s;
}

.button span:after {
  content: '\00bb';
  position: absolute;
  opacity: 0;
  top: 0;
  right: -20px;
  transition: 0.5s;
}

.button:hover span {
  padding-right: 25px;
}

.button:hover span:after {
  opacity: 1;
  right: 0;
}


body {margin:10}

.icon-bar {


	height: 100%;
    width: 90px;
    position: fixed;
    z-index: 1;
    top: 0;
    left: 0;
    background-color: #555;
    overflow-x: hidden;
    padding-top: 0px;
}

.icon-bar a {

	text-align: center;
	padding: 6px 8px 6px 16px;
	transition: all 0.3s ease;
    text-decoration: none;
    font-size: 36px;
    color: #white;
    display: block;
}

.icon-bar a:hover {
    background-color: #4289b5;
}

.active {
    background-color: #4CAF50 !important;
}

.mainsbar {
    margin-left: 160px; /* Same as the width of the sidenav */
    font-size: 28px; /* Increased text to enable scrolling */
    padding: 0px 10px;
}
@media screen and (max-height: 450px) {
    .icon-bar {padding-top: 15px;}
    .icon-bar a {font-size: 18px;}
}


body{
  font-size: 20px;
  font-family: Roboto;
  font-weight: 300;
}

a{

  text-decoration: none;
  ;
  padding: 10px 15px;
  line-height: 3;
  -webkit-transition: all .3s ease;
	   -moz-transition: all .3s ease;
	    -ms-transition: all .3s ease;
	     -o-transition: all .3s ease;
				  transition: all .3s ease;
}

a:hover{
  color: #FFF;
  background: #FC2121;
  -webkit-transition: all .3s ease;
	   -moz-transition: all .3s ease;
	    -ms-transition: all .3s ease;
	     -o-transition: all .3s ease;
				  transition: all .3s ease;
}

body {margin:0;}

.icon-bartop {
	overflow: hidden;
    background-color: #333;
    position: fixed;
    top: 0;
    width: 100%;
    background-color: #555;
    overflow: auto;
}

.icon-bartop a {
    float: left;
    width: 20%;

    text-align: center;
    padding: 12px 0;
    transition: all 0.3s ease;
    color: white;
    font-size: 20px;
}

.icon-bartop a:hover {
    background-color: #000;
}



.active {
    background-color: #4CAF50 !important;
}

.main {
  padding: 0px;
  margin-top: 80px;
  height: 1500px; /* Used in this example to enable scrolling */
}

最佳答案

您可以将顶部位置设置为84px ...，因为您使用的是固定位置，并且可以使用cal（）计算高度。



console.log('Loading')

.button {
  display: inline-block;
  border-radius: 4px;
  background-color: #4CAF50e;
  border: none;

  text-align: center;
  font-size: 28px;
  padding: 20px;
  width: 200px;
  transition: all 0.5s;
  cursor: pointer;
  margin: 5px;
}

.button span {
  cursor: pointer;
  display: inline-block;
  position: relative;
  transition: 0.5s;
}

.button span:after {
  content: '\00bb';

  opacity: 0;

  right: -20px;
  transition: 0.5s;
}

.button:hover span {
  padding-right: 25px;
}

.button:hover span:after {
  opacity: 1;
  right: 0;
